BRACELET HOOK.

Application filed April 27, 1926. Serial 110.10%,919.

lets having diiferent Widths for each style of bracelet carried in stock, and to accomplish this in a simple and practical way, I have provided an improved hook of this character which: has separate members mounted therein adapted to swing or move outwardly under spring pressure to extend the working width of the hook whereby they may be readily adjusted to cause the hook to tit watch bails of different widths; and the following is a detailed description of the present embodiment of my invention and showing one construction of bracelet hook by which these advantageousresults may be accomplished V With reference to thedrawings, designates my improved bracelet hook, the same being composed of a body portion 11 with a shank portion 12 and a hook portion 13, also a spring tongue 14 for closing the hook, the tongue beingsupported tion of the hook. I v

My invention provides a means by which the working width ofthe engaging portion of the hook may be varied and to accomplish this in a, simple and effective way, have provided a pair of plates or wings 15 which are herein shown as being connected together by a U-shaped spring16. These plates are shapedto lie'against the back or shank portion of the hook with their outer ends 17 curved to conform to the curved shape of the engaging portion 13 of the hook. hese plates being so shaped are adapted to slide laterally on the inner side of the hook portion and are preferably normally pressed outwardly by action of the spring 16, thelimit of the outward motion. being that of the enlargements 18 of the ends of the wings where they are connected to the ends of the spring which bring up against the inner walls of the shank portion of the hook and the edges of these plates are so shaped as to slide over the edges 19 of the side walls of the shank over whic they work while sliding toward and from extended position. v I have herein shown the wings or plates as being pres'sedtoward extended position by a U-shaped spring but this spring may be omitted if desired and the wings mounted in the hook to. remain in any desired position therein. By providing a U-shaped spring the swing of the arms occurs at spaced points adjacent the edges of the body whereby the This invention relates to an improved -construction of so-cali d bracelet hook; and has for its. object to provide a hook of this character adapted more particularly for connecting an end of a bracelet to the bail oi a Wrist watch or the like, the hook beingprovided with laterally-extending inembers adapted to be adjusted to vary the operating width of the hook so as to it watch bail members of diiierent widths.

A further object of this invention is to mount a pair of laterally-extending members in this bracelet hook, a portion of these members being curvedto conform to the curved portion of the hook, and a spring may be provided for normally pressing these members toward expanded position.

'With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings:

Figure 1 is a front view showing a portion of a watch with the bail member to which my improved adjustable hook is attached showing the extensible wings or members in extended position.

Figure 2 is a sectional plan view showing the laterally extensible members as mounted in the curved portion of the bracelet hook and connected together by a U-shaped spring.

Figure me as Figure 2 but show- 8 is the sa ers in contracted ing the extensible memb position in the hook.

Figure 4 is a sectional side elevation showing one of the extensible members as having a portion curved to conform to the shape of the hook.

Figure 5 is a se Figure 4:.

Figure 6 shows the extensible members with the curved portion in section and as connected by a Ushaped spring.

Figure 7 is a perspective view of the under side of my improved hook showing the extensible members mounted therein.

. It is found in the practical construction and operation of watch bracelet hooks; of advantage to provide a hook of this character having means whereby its width may be readily varied to fit watch bails of different widths so that merchants selling the same will not be obliged to carry a stock or bracection on line 5-5 of in the body porf hook ends of the Wings remain substantially in line with the hook portion of the body on being swung to extended position.

My improved extension hook is very simple and inexpensive in construction and is effective in its operation and by its use a bracelet hook may be caused to fit Watch bail members of different widths.

The rear end of my improved hook may be constructed to be attached to any type of bracelet element, but I have herein shown two pairs of fingers 20 adapted to be folded to engage the end link of a bracelet of open loop formation.

The foregoing description is directed solely towards the construction illustrated, but I desire it to be understood that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by the terms of the appended claims.

. I claim:

1. A bracelet hook comprising a body portion with. a hook at one end and having an adjustable laterally-extending member cooperating with the hook for regulating the operating Width of the engaging portion of the hook.

2. A bracelet hook comprising a body member having a shank shaped at one end to form the hook and a laterally adjustable member carried by and cooperating with said hook for varying its operating Width.

3. A bracelet hook comprising a body member with shank and hook portions a relatively movable member in said hook portion, and a spring acting on said member to move the same to extended position to vary the operating width of the hook.

4. A bracelet hook comprising a body member having a hook at one end thereof, and a pair of spring-pressed lateral extensible members in the hook portion to vary its operating width.

5. A bracelet hook comprising a body member shaped at one end to form a hook, and a pair of plates mounted to slide laterally in said hook portion to vary its operating width.

(5. A bracelet hook comprising a body member ha ing a hook at one end, and a pair of spring pressed members connected together by a U-shaped spring acting to spread said members relatively laterallyin the hook to vary the operating width of the hook.

7. A bracelet hook comprising a body member having a hook portion at one end and a pair of separable plates each having a portion curved to conform to the shape of said hook portion and slidable laterally in said hook to vary the operating Width of the hook.

S. A bracelet hook comprising a body member having a hook-shaped portion, a pair of separable plates hook-shaped at one end and slidable laterally in the body hook, and a spring housed in the body member acting on said plates to move them toward extended position to vary the operating width of the body hook.

9. A bracelet hook comprising a body portion a pair of laterally adjustable hook members. means for mounting said members in said bodyv to swing laterally from spaced points adjacent the edges of said body for regulating the operating Width of the engaging portion of the hook.

In testimony whereof I atlix my signature.
